    Many sociologists now assert that the long-term success of a society is dependent on its ability to socialize its young adult males -- in the sense of finding gainful employment for them in order to keep them busy and useful. Failure to do so -- for example, in inner cities in the United States, or in several African countries -- results in increased crime, civil unrest, etc. Apparently having a large number of testosterone-crazed individuals hanging around idle is a Bad Idea.

    Certainly this model has been used in a lot of science-fiction stories -- everyone gets a minimum stipend and lives on the productivity of the machines and a few humans. I've always wondered about the overall economic feasibility of such a system, and how we get from here to there. Here's a sample of questions -- many good stories have been written trying to answer some of them.

    • What standard of living will be produced? Will it be like I have now -- single-family house where everyone has their own bedroom, two cars, some amount of luxury? Or like things were when I was in college -- three people in a two-bedroom apartment, one car amongst them (and that 11 years old), no one ever ate out, etc? Or like rural India -- a family of five in a one-room hut?

    • Supply and demand have to balance in some fashion, so we need productivity to increase to the point that, say, 10% of the population plus the machines can produce enough goods and services to meet the demand. Some production should be simple, but will the humanoid robots be able to build or (more difficult) repair a house on site? Deal with the individual complexities of surgery? Teach small children? Settle a domestic dispute?

    • Who decides which people work and which don't? Are there tests? You're smart, you have to work and oversee the machines; your neighbor isn't, she gets to live the life of leisure. What if your neighbor wants to work, but has no skills that are useful?

    • Today, labor is taxed heavily and capital is taxed lightly -- look at how much of the total tax revenue derives from payroll and personal income taxes. You have to change to a system where capital is taxed heavily (your "taxes paid by those companies"), since there won't be enough labor to tax. Today's rich people are going to use some part of their money fighting that, and at least in the US, money appears to be quite persuasive.

    Before anyone rushes out to try this, some basic questions about SCO's ownership arrangements:
    • In addition to the common stock, are there any special classes of shares? Some companies have "super-voting" classes where the special shares get 100 or 1000 votes per share. See, for example, Comcast prior to their deal with AT&T Broadband; the Roberts family held roughly 2% of the equity, but had over 80% of the votes.
    • What fraction of the shares are held by parties who may not be interested in selling at this time? If, for example, some small group already controls 51% of the shares and is willing to speculate on SCO winning the lawsuit (in which case those shares will be VERY valuable), they won't sell and no one else can gain control.
    • Are there any provisions in the corporate governance arrangements that require more than a simple majority? Perhaps changes to the board of directors require a super-majority?

    There's no sense buying a share or ten unless you have a reasonable expectation that you can achieve the goal of controlling the company and making the changes that you want.

    IANATA (I am not a tax accountant), but I believe that, in the U.S., whether you get bit by this depends on what you do with the options. I think the tax bind goes like this:
    • You get 1,000 stock options with a strike price of $1.
    • At some point when the stock price is $51, you exercise the options and take the stock. You have an immediate taxable income of (51-1)*1000 = $50,000.
    • Later in the same year the stock and/or the market tanks and your shares go to say, $1 per share.
    • If your other income has pushed you into the top tax bracket (38%), you owe $19,000 in income tax on the option income. Even if you sell all of the stock, getting $1,000, you still have to come up with another $18,000 from somewhere to pay the taxes.

    If your total income is high enough, you may also run into funky things with the Alternate Minimum Tax. Like many other past episodes involving U.S. taxes, the AMT is not indexed for inflation, so that a law intended to affect only the wealthy has, 20 years later, started biting the upper middle-class as well. At one point, some Senator said something like, "If we had voted for the kinds of tax rate increases that inflation and non-indexed tables have given us, none of us would have been re-elected."

    I'm a chicken myself, and when I had the opportunity to exercise the small number of options that I had received, I used the "stockless" arrangement the company had set up -- the custodian sold my shares at the market price, subtracted the strike price from the proceeds, and sent me cash. It was all treated as straight income (no chance to exploit the lower capital gains rate), but no unexpected surprises at tax time either.

    Like many other things -- steel, autos, DRAM -- the world now has the capacity to produce, and is producing, more engineers than it can efficiently use. Based on simple supply and demand, the price paid for engineers (wages) should fall.

    When China built massive new steel production facilities, did they know that those mills could produce far more steel than China could use domestically? Without a doubt. But their cost structure is low and they planned to export the excess. Do they know that they don't need that many new engineers every year? Almost certainly, and they'll attempt to "solve" the problem the same way they solve their steel problem -- export.

    IIRC, the fundamental limit set on balls by the USGA is that they shall not exceed an initial velocity of 250 feet per second (FPS) when hit on the USGA's standard hitting machine, and the machine hasn't changed in decades. There have been a variety of improvements in aerodynamics (ie, dimple design) that have improved things, but I don't think that's made an enormous difference. You've always been able to buy illegal "hot" balls, but the pros certainly aren't using them. Improvements in clubs -- compare the weight of a modern titanium-head graphite-shafted driver with an old maple-head steel-shafted one -- allow for higher clubhead velocities and resulting initial ball velocity. IIRC, modern pros get much higher initial velocities than the standard hitting machine, independent of ball technology.

    For the average player, I believe that the biggest change has been the use of modern materials to lighten overall club weight and improve the distribution of head mass to produce a much larger "sweet" spot. That combination makes it easier to make solid contact with the ball, producing better energy transfer and greater average distance. OTOH, I don't think it has made the average player much better -- at least I haven't noticed that the average players' scores have improved dramatically.
